(CNN)Nine members of a Mormon community were killed on the Mexican side of the US-Mexico border, and authorities are investigating whether the attack was the result of mistaken identity.
The slain victims include three women, four small children and two infants, family member Alex LeBaron said from Mexico. He said all nine were dual US-Mexican citizens.
The victims were “all shot while in vehicles while driving,” LeBaron told CNN. Several children survived the attack.
Investigators believe three vehicles traveling between the Mexican states of Sonora and Chihuahua were ambushed by criminal groups Monday evening, Mexican authorities said.
